'3 Claims:

This invention relates to safety appliances in the nature of a goggle assembly designed to protect the eyes of the wearer, and the primary aim is to provide such an article of manufacture as will fulfill the objects of immediately conforming to the contour of the face of the wearer adjacent to the eyes when donned and will have the further property of having a transparent cover or front adapted to be replaced without employment of instruments or tools and through the utilization of the inherent resilient characteristics of the frame thereof.

Other important objects of the invention include the manner of forming the structure at the zone of interconnection between a tubular frame and cover to prevent accidental displacement and to establish requisite, practical interlocking; and the provision of cooperating interengaging elements on the cover and frame to lend structural rigidity to the aforesaid interlocking and to prevent spreading of the tubular frame.

Other objects of the invention will appear during the course of the following specification, referring to the accompanying drawing where- Fig. 1 is a perspective view of the goggle assembly embodying the invention.

Fig. 2 is a perspective view of the cover or front thereof entirely removed from its association with the remaining parts of the assembly.

Fig. 3 is an enlarged, fragmentary, front elevational view of the median portion of the goggle assembly, parts being broken away to reveal the reinforced interlock between the frame and cover. I

Fig. 4 is an enlarged, detailed, fragmentary, sectional view taken on line IV-IV of Fig. 1.

Fig. 5 is a similar view taken on line V-V of Fig. 1; and,

Fig. 6 is an enlarged, fragmentary, view taken on line VI-VI of Fig. 1.

The chosen illustrated embodiment of the invention comprises a tubular frame of resilient substance broadly designated by the numeral It and a cover I2 of transparent material closin one end of the frame and removably held in place by specially-formed, cooperating elements hereinafter specifically defined. One end of frame I0 is contoured to substantially conform to the face of the wearer when the goggle assembly is maintained in position through the medium of a head-encircling elastic band I4.

This band I4 is anchored to frame In as detailed in Fig. 6. A pair of loops I6 formed intesectional 'grally with frame I0 and in relative parallelism is disposed at each end of frame I0; and elastic band I4 will be securely fastened when threaded around the loops I6 as shown in Fig. 6. Obviously, the employment of these loops I6 obviates the necessity of perforating frame III and there"- by presenting the possibility of allowing foreign matter to enter the frame when the goggle assembly is donned.

The end I8 of frame III which is contoured to fit th face merges with a nose engaging sec-- tion 20 that extends inwardly on the median line of frame I0. Thus, the end of frame It opposite to contoured edge I8 presents an opening having a periphery in substantial conformity with the shape of the edge of cover I2 shown in Fig. 2. The marginal edge of cover I2 snuggly fits into an inwardly-facing groove 22 formed in frame In at the end thereof opposite to contoured edge I8.

That portion of groove 22 along the normally upper edge of cover I2 and at the upper portions of the ends of said cover is arched as shown in Figs. 4 and 6 to receive the similarly arched marginal edge of cover I2. Notch 24 provided on the median line of cover I2 receives nose-engaging section 20 and is specially formed as shown in Figs. 2 and 3 with respect to the provision of opposed shoulders 26.

Cooperating shoulders 28 provided on frame III within the groove 22 thereof at the noseengaging section 20 rest against shoulders 26 on cover I2 when elements ID and I2 are assembled, and rigidity attended by a positive reinforced interengagement is assured by the provision of a flexible, U-shaped insert 30 having its ends at shoulders 28 and disposed to bear against shoulders 26 when cover I2 is fitted in place.

These shoulders 25 are opposed to portions of the arched marginal edge of cover I2 to such a degree that any tendency on the part of frame II! to spread laterally will be prevented. Insert 30 is sufficiently resilient to permit drawing together the ends thereof when cover I2 is to be removed for replacement.

No special tools are needed to manipulate tubular frame II] when cover I2 is being removed Or inserted, and a damaged cover may be replaced with speed and ease when necessary.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A goggle assembly comprising a tubular frame; and a cover of transparent material closing one end of the frame, said frame having an inwardly-facing groove, arcuate in cross section, formed therein at said one end thereof for receiving the marginal edge of the cover, said cover having an arched flange at its said marginal edge to substantially conform to the arcuate form of said groove, whereby to enter the same and prevent accidental lateral expansion of the frame.

2. A goggle assembly comprising a tubular frame; and a cover of transparent material closing one end of the frame, said frame having a nose-engaging section integral therewith and projecting inwardly at the median line of the frame, said cover being provided with a notch to receive the nose-engaging section, said frame having an inwardly-facing groove, arcuate in cross section, formed therein at said one end thereof for receiving the marginal edge of the cover, said cover having opposed shoulders created on the edge thereof forming the said notch, said frame having cooperating shoulders formed in the groove thereof at the nose-engaging section to engage said shoulders on the cover, said cover having an arched flange at its said marginal edge to substantially conform to the arcuate form of said groove, whereby to enter the same and prevent accidental lateral expansion of the frame.

3. A goggle assembly comprising a tubular frame; and a cover of transparent material closing one end of the frame, said frame having a nose-engaging section integral therewith and projecting inwardly at the median line of the frame, said cover being provided with a notch to receive the nose-engaging section, said frame having an inwardly-facing groove, arcuate in cross section, formed therein at said one end thereof for receiving the marginal edge of the cover, said cover having opposed shoulders created on the edge thereof forming said notch, said frame having cooperating shoulders formed in the groove thereof at the nose-engaging section to engage said shoulders on the cover, said cover having a flexible, U-shaped insert embedded therein, said insert having ends bearing against the shoulders of the cover when the frame and cover are in an assembled condition, said cover having an arched flange at its said marginal edge to substantially conform to the arcuate form of said groove, whereby to enter the same and prevent accidental lateral expansion of the frame.
